[AUCTeX] LaTeX: problems after [0] pages. compile problem

[Graham Smith]

I am getting the same problem on Linux (ubuntu) and aquamacs on a simple 4 line bit of latex, which compiles on the same box using other editors, so it seems its specifically an Emacs/Aqumacs/Auctex problem. 

The full error message is (from aquamacs):

Running `LaTeX' on `newtest' with ``pdflatex  -interaction=nonstopmode "\input" newtest.tex''
/bin/sh: line 1: pdflatex: command not found

LaTeX exited abnormally with code 127 at Mon Aug 11 23:17:45

Not sure which is the best forum to ask in, but I am hoping the expertise will be here to help me fix this.  This was working on both Ubuntu and the Mac before recent emacs/aquamacs upgrades. so I assume I have killed something, just don't know how to fix it.

Many thanks,

Graham
